In this specification, and the accompanying drawings I shall describeand show a preferred formof my invention; and specifically mentioncertain of its more important ob-l r9 isprovided, said flange beingpreferably 0cast integral therewith, has formed upon its inner face aseries of ratchet teeth20, which.

jects. I do not limit myself to the vform disclosed, since variouschanges and `'adaptations may be made therein without departing from theessence .of my invention as hereinafter claimed; and objects andadvantages, other than those specifically mentioned, are included withinits scope. i

This invention relates to` turnstiles, and

moreespecially to turnstiles for use in chain 'y stores and the like. l

VAn object of the invention is to provide an improvedhead constructionfor turnstiles in which therotary part is furnished withnovel meansforcontrollingthe direction of rota-V tion thereof. j

Otherobjects of the invention are to, in

general, simplify and improve upon the con-y struction of turnstilesthereby rendering them more durablemore dependable in operation, andless apt to get out of order.'

Other objects,fadvantages and featuresof invention mayhereinafter-appear.

Referring to the accompanying drawings which illustratewhat is atpresentdeenied to be a preferred ,embodiment of the invention,

Fig. 1 is a topplan view of the head portion, partsbeing removedltodisclose underlying construction. i y l v Y Fig. 2 is a plan view of thehead cover.

Fig. 3'is a mid-sectional view of Fig. 1 in' top of post 7 is .secured akhead'f8 which, by 1 preference and as shown,.consists of avhori``zontalcircularplate 9 having an upstanding peripheral flange 10. Saidplate 9 is desirably attached to the postf'vb'y means of screws 12, andis provided with a central aperture 13 which is disposed axially of saidpost. i

Upon the top of headl 8 isloosely mounted a circular cover plate 15which iszofthe same i diameter as said head 8. Said cover plate 15 has acentral aperture 16 which corresponds 4 is a perspective View of thecomplete in size to the aperture 13 through plate 9 and aperture. j

The upstanding flange with which plate however,lare not arranged toreceive a pawl for movement in one direction only, but `are of equallength and slope on both sides of each tooth, thereby adaptingthem forcontrolling the ,movementy of av pawl-carrying member in bothdirections, as will hereinafter be described.

Within the internally toothed ratchet member provided by the flange 10,is' mounted lwhich is located directly above the latter a rotatable bar21 whichis provided with a" i bore or hole 22. Said bar 2l issecuredtothe lower side of disc by means of any suitable fastening device such asscrew 23. With the bore '22 of said bar brought into alignment with theaforementioned holes 13 and 16, a

lag screw 25'is inserted throughl these alignedk l openings inV ordertoprovide a pivot whereon the plate l5l` and bar 21 may rotate. i Y Itwill be seen that said bar 21 is shown sei cured in place solely'bymeans of the single attaching screw23 in conjunction with the pivot pin25, said pin extending through the central portion of said bar, and thesingle at-V taching meansprovided by the screw 23 eX- along yits length.Althoughbut a minonfeaf ture of thevinvention, yet this Ysimplified..

structure is not without its importance.

pawlordog 28 bymeansof a pivot pin 29. l The actions of saidpawl arecontrolled by `means of a tension yspring 30, one end of said springbeing securable to either 'end portion receive aremovable pin 2lbwherebythe tenj tending through said bar ata different point l of saidpaWl, and the other end of said spring r being securable to either sideof saidbar. In Fig.1, said bar 21 is shown provided at each l side withasocket 21a which is adapted to sion spring 30 may be secured to `eitherside y portion of said bar. A Eachl endof said pawl 28 is provided withan aperture 28a to provide for Vsecuring the adjacent end of springthereto by means of a link or pin 28o. It Will thus be seen that saidspring is reversible in order to position either end of the pawlforcooperation with the ratchet teeth 20.

The turnstile head is preferably provided with four equally spacedradial arms 35,

which may be made of woodand which are in that casemortised together attheir'intersection so as to all lie in the same plane.` A' central hole36 is provided through these -`arms',-

to provide for insertion of the lag screw 25.

Returning again to plate or disc 15 whichise,

loosely seated upon the top of the head or member 8, said plate 15 maybe a casting and in any case is provided near its periphery with fourequally spaced upstanding lugs '40, each'y of said lugs having a right'angled inwardly projecting corner portion which is adapted to fitbetween the external angles of the assembled arms 35. A plurality ofscrews 46 are provided to secure the arms to the up'- per side of plate15.

An ornamental member 45 may be secured' tothe top and central portion ofthe device by means of pins 46. Y

Between its bifurcations bar 21 is provided with'a curved crotch portion210 which forms n Y a stopl for pawl 28 in whichever ofthetwo positionssaid pawl may be mounted. This constructiony limits the action ofl thespring and also permits the turnstile to be rotated only in thepredetermined direction desired.

In assembling the various parts of the device, the base plate 9 of thenonrotatable head 8 is iirst secured in place o n the top of the post 7with the opening 13v of said plate located axially of said post, thescrews 12 be? ing inserted through openings provided there for insaid-plate 9 and screwed into the top of the post. Then the bar 21,towhich the pawl 28 and spring 30 have previously been attached, issecured to `one side of the cover platev 15-by means. of the screw 23 insuch a manner that the bore 22 through said bar may be brought intoalignment with the bore 16 i through said plate 15. Then the operatingarms 35 which have previously been mortised togetherat their centers' atright angles to cach other, are secured tothe side of the plate 15opposite to bar 21 by means of the screws 42, the opening 36 through thecentral portions of said bars being positioned in 'alignment with theopening 16 through thev plate 15. Said arms 35, will of course, be,circumf v ferentially adjusted to cause the' lugs 40 to fit into-the'angles between the adj acent' arms.

Next the opening 16 ot plate 15 and bore22;

of bar`21 are brought into alignment-With eachother and the Vlag', screw25 is screwed downwardly into the top of the post 7 in the positionshown. Lastly the ornamental mem-` ber 45 may be centrally attached bythe pins 46 to the top of the device, as shownf f When it is desired tochange the position 1.a In a turnstile, a rotatable head, and anonrotatable support upon which said head iss-mounted, there-being asingly pivoted reversible pivotally mounted double acting.
